To all "whom it 'may/ concern:

Be it known that l, Airrniin F. Poona, a citizen of the United States,residing at Chicago, in the county of Cook and Illinois, have inventedcertain new tul Improvements in Accounting Systems, (Case 12) of whichthe following is a lull, clear, concise, and exact description,reteronce being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to an electro-mcclianical system of accounting forautomatically taking care of an employees time and wages.

In particular my invention comprises a system of accounting in which theindividual wag-eand time-registers are actuated by a step-bv-stepmovement, this actuation being controlled by electro-magnetic means.However, the totalizing regi ters connected with certain of theindividual registers are operated through the medium of differentialgearing which properly connects each totalizing register with itscorresponding individual registers.

Furthermore, my invention contemplates a system whereby the particularrate at which a certain individual register shall be operated may befreely selected by simply inserting a connecting plug in any particularjack. The insertion of an employees plug in any one of a series of jackswill, at predetermined intervals, cause the closing of a circuit throughthe corresponding registeroperating devices, to control the actuation ofthe registers associated with such devices.

In order to make provision for number of different rates atwhich anygiven register maybe operated, I employ series of rate-disks mountedupon a time-controlled shaft. Each of these disks is provided ith apeculiarly grooved periphery in which en a contact-closing device, soarranged that the'rotation of the disk with which it'is associated willcause movement of the device to one side or the other for the closing ofand use the circuit which causes the operation of the 7 devices thatactuate the registers. Just how this is effected will become apparentwhen the description of the drawings is taken up in detail.

These and other objects and advantages electro-magnet-ic of my inventionwill become apparent as the specification proceeds.

tfitate of in the accompanying drawings, wherein like referencecharacters are used to indicate 7 corresponding parts, 1 igure l 18 adiagraun matic 'epresentation of one bodimeiit of my system, 4represents in detail the register-artuating device. Fig. ll is a sideview, as appearing wheu looking in the direction of the arrow associatedwith Fig. ot' the series of these register operating devices arrangedupon a common shaft, Fig. a shows in detail a register oper ating deviceconstructed to actuate its associated reistcr in a direction oppositetothat practical emin which the device indicated in 2 actu ates itsregister, Fig. 5 is a fragn'ientary dctail view, partly incross-section. showing a convenient. form of dili'erential gearing usedin connection with the totalizing registers, Fig. (5 is a fragmentaryview showing a do 'elopment in plan oi the periphery of one of the ratedisks, and F T shows-a rearrangen'ient of certain portions of thecircuits in the diagram ot l ig. 1. The object and purpose of thisarrangement will be de scribed later on.

in order that the. operation oi the system as illustrated in Fig. 1 maybe more readily understood, I will first take up the description indetail of the regis operating devices as illustrated in Figs. 2, 3. andi.

Referring particularly to Fig. 2 and to the first (or third) of thedevices shown in l. Fig. 3, it will be noted that the ratchet wheel 1 isloosely mounted on the shaft 2.-

This shaft, of course, is, at its ends, mounted in suitable hearings inthe casing inclosing the parts, the lengths ofthe shaft being determinedby the number of register operating devices which it is desired toemploy. Rigidly secured to the ratchet wheel is the gear wheel 3 so thatthe two wheels may be rotated together as one. As shown most. clearly inFig. 5, a pinion l is mounted coir trally in its composite wheel formedby the ratchet 1 and the gear 3. Sleeves 5 and (3 are looselymountedupon the shaft 2 upon opposite sides of the composite gear and ratchetwheel, and their adjacent ends are provided with bevel gears 7 and 8respectively, which engage with the bevel pin ion 4. just referred to.The opposite ends of these sleeves are, of course, likewise pro videdwith bevel gears 9 and 10, which are adapted to engage with theassociated bevel pinions mounted in the corresponding gear and ratchetwheels.

end of its armature 21' will cause the same This showing has not beenmade in Fig. 5 for the reason that it would simply be a duplicate of thedifferential gearing therein illustrated. the instance shown, the gearand ratchet wheels are secured together by means of screws or bolts 11,which at one end carry lugs or projections 12. The purpose of these lugswill bejhresently set forth.

As seen. from Figs, 2 and 3 the gear wheel at each register operatingdevice is adapted to mesh. gear wheel 13 mounted upon a countershaft14C, suitably supported. This gear wheel 13 engages with a gear 15,which,

in turn, is operatively connected with the first of a series of properlyinterconnected indicating wheels lb, 17 and 18, as clearly shown in Fig.3. An electro-magnet 19 is mounted in appropriate relation to theratchet wheel. Pivoted to the frame 20 of the suppor for; theelectroqnagnet, is the armature2i which, at its outer end, carries theratchet actuating pawl. 22. This pawl is loosely pivoted on the armature21 and is by gipflity held against the teeth of the ratchet, asindicated in Fig. 2. A second electro-magnet 23 is mounted in proximityto the ratchet. wheel in the relation shown in l Fig. 2. Thiselectro-magnet 23 is polarized and its windings are in series with thewindings of the electro1nagnet 19. This series arrangement of thewindings of the two electro-inagnets is indicated in Fig. 2 by the wireconnection 24:. The armature 25' of electro-magnet 23 is pivoted to asuitable framework at 26, and is provided with an arm or extension 27.The lower end oi": the armature 25 is provided with an adjustablecounter-weight 27.

A sufiicient number of parts of the register operating device hasnowbeen-described to ii'ord an understanding of'the operation of thedevice. Supposing, now, that the circuit through the electromagnets hasbeen i closed so that the same will be energized, this momentaryenergization of the electro-:

magnet 23 will cause the armature 25 to be rocked so that the lower endwill be drawn against its associated polepiece of the electromagnet.With the armature in this position the center of gravity will, by virtueof the counter-weight 27 have been thrown to l the right of thepivot-'26. This rocking of i the armature will liftthe arm. 27 upwardly1 out of the path of the top lug 12. At the same moment that theelectro-magnet 23 is l energized, the electrognagnet 19 will also beenergized and in attracting the lower to hero-shed into the positionindicated in dcted lines in Fig. 2. This will cause the act. L 1g pawl22 to drop into the.

lower tooth.

When the circuitthroug l ed at the next moment, GXtGHSlOIl 21 or l thearmature 21 will be forced to the left through the action of the spring28, thereby causing the pawl 22 to move the ratchet wheel one tooth tothe left, that is to say, in the direction indicated by the arrow. Thedeenergiaation of the electro-magnots will not afi'ect the position ofthe armature 25 for the reason that gravity will retain it in theposition.- to which it was moved when the iii-st energization of theelectro-mag'net 253 tool; place, so that during the successiveeneroiza-tions of the electro-magnet 19, the arm 2'? will remain out ofthe path of the lugs 12, except. as hereinafter specified.

Movement of the ratchet wheel in a diroction contrary to that indicatedby the arrow is prevented by the retaining pawl 29 pivoted to a suitablesupport at 30. This pawl is kept by gravity in the path of the teeth ofthe ratchet wheel, and while it pcrniits movement of the same in thedirection indicated by the arrow, it positively prevents rotation in theopposite direction, as may be clearly gathered from what is shown inFig. 2. Now it may be necessary at certain times to decuuiulate theregister, that is to say, to bring it back to zero. In this event, it.is, of course, necessary that the ratchet wheel be allowed to rotate inthe direction opposite to that indicated by the arrow in Fig. 2. Toprovide for this contingei'icy l'have arranged a rod 31, slidablymounted in a framework and provided at its outer end with a manipulatingknob The lower or inner end oi. this red has secured thereto apeculiarly shaped extension Set. The arm of this extension engages atits free end a lug 36 on the arm 27 of the armature 25. The arm of thisextension engages at its free end a lug 38 on the actuating pawl 22. Thecentral projection 39 of this extension 3s has a slotdO at the bottom ofwhich rests a lug on the retaining pawl 25). This log and slotengagement between the rod 31 and the retaining pawl 29 permits thelatter to ride over the teeth of the ratchet wheel. l l heir the rod 31is pulled up, it will carry with it the arm 27, retaining pawl 29, andactuating pawl 22, gagement between the'extension 34 and the lugs onthose parts. In other words, when the rod 31 is moved upwardly, the arm27 is moved out of-the path of the projections 12, the retaining pavv'l29 is moved out of the path of the ratchet wheehas is also;actasting"pawl 22. With the parts in this condition it is plain .tosee that theratchetwheel is free to "move in a direct-ion to permit deer, dation ofthe associated register. in or that the rod 31 may not be accidentallyMoved from one position to the other, l supply a retaining means in theshape of wedge shaped block 42 on the rod a cobperating spring 43mounted on the support '32. iwhth the rod in the position.

all by virtue of the enshown in Fig. 2, it will be seen that thetendency of the spring 43 is to hold it in that position; while with therod in its drawn out position, the spring 43 will engage with theopposite side of the wedge shaped block 42 and tend to retain the rod inits drawn out or elevated position. The movement of the extension 21 ofthe armature 21 is limited by the lugs a4 and secured to a suitablesupport. From this description of the construction and operation of theregister actuating device, it will be seen that at every interruption ofthe cur-. rent sent through the winding of electromagnet 19, the ratchetwheel will be moved a distance of one tooth, and, of course, theassociated register will be actuated correspondingly.

Now, the rate of actuation of the register associated with theparticular actuating device, will, of course, depend upon the number ofcircuit interruptions that occur in a given time. The means for causinga predetermined number of current interruptions to take place in a giventime through the windings of the register operating device shown in Fig.l, and comprises a series of what. I term rate disks 4L6, 4'7, and 48mounted upon the time controlled shaft 49. It will be observed that eachof these disks is provided with a periphery that is grooved in a.peculiar manner. In order to understand best the purpose and object ofthe outline of the peripheral groove on each disk, attention is directedto the illustration given in Fig. 6. The distance indicated by thedotted line 46 represents the developed periphery of the rate wheel ordisk e6. Looking at the groove or channel bounded by the line 46, itwill be seen that there are three upwardly projecting portions 46a. Ofcourse when I say upwardly I use the term with reference to Fig. (3only, it being understood that the direction in which these projectionsextend depends upon the direction in which .the disk is viewed.Following these three upward projections in the peripheral groove orchannel of the disk 46 is a series of seven projections deviating in adirection opposite-to that of the projections 46d. For the present it issuflicient to say that each one of these projections or deviations, asthey might as well be called, in the. groove of disk 46" represents anapproximately momentary closing of the circuit through the windings ofthe electro-magnets 19 and 23. However, inasmuch as deviations 46a arein a direction opposite to that of the deviations 466, it will beapparent that the first three current impulses sent through the windings19 and 23 will be opposite to the seven succeeding current impulses, butinasmuch as the electro'magnet 19 1s a nonpolarized one, the particulardirection of the current traversing this'winding has no effect upon itsattraction of the armature .21. This, however, is not the case with thepolarized electro-magnet 23. Starting with the first current impulse,the energization of the mag net 2-3 will be such that the armature 25will be rocked to cause the lower end thereof to be drawn against theattracting pole, as already mentioned. The second and third impulsesthrough the electro-magnet will not disturb the position of the armaturebrought about by the first impulse, tor the reason that the tendency ofthese second and third impulses would be to draw the armature into thesame position into which it was drawn by the first impulse. However, thefourth impulse, which in Fig. 6 may be said to be represented by thefirst of the downwardly extending deviations +1.61), will rock thearmature 25 into the position indicatcd in Fig. 2. Inasmuch as thesucceeding impulses, namely impulses 5 to 10 inclusive, are in the samedirection as the fourth impulse, the armature 25 will remain in theindicated position and leave the arm 27 in the path of the lugs 12.

As indicated in Fig. 6 where the distance marked off by line 4-6includes the developed periphery of the disk 4:0, after the tenthcurrent impulse has been sent through the electro-magnets of theregister operating device, the next impulse will he the one representedby the first of the deviations 4-60; This means that after ten currentimpulses (which, of course, are essentially accompanied bycoi'ipsponding current interruptions) have been sent out into thewindings of the clectrounagnets, the eleventh impulse would beidentical, so tar as graphic representati on is concerned, with thefirst impulse represented by the first of the three deviations 46a. Fromthis it might truly be said that ten current impulses, (or ten currentinterruptions) constitute what might really be termed acycle. I findthis term not only to be correct in properly expressing the currentimpulses or interruptions, but I find it convenient to explain how theother rate wheels or disks produce diti erent rates of opeiation of athe corresponding registers. For the sake of presenting a concreteillustration it might be supposed that the disk 46 actuates itscorrcsporniling register at a rate which represents five cents an hour,which the corresponding wage register would indicate. If, therefore,disk 46 represents a five cent rate and the number of currentinterruptions caused by the disk during one rotation thereof is equal toten, or one cycle, it is plain to see that the disk 47, if it is torepresent a ten cent rate, must have a periphery so grooved that it willcause during one rotation thereof, twice the number of current impulsesor interruptions to be sent through the windings of the particularregister actuating device. By looking at Fig. 1

' gether with number of tended to represent, in conjunction with theadjacent fragment, a development partly broken away, of a diskrepresenting at higher rate than that represented by disk 46, Disk 48has been assumed to represent a fifteen cent rate. In order to do thisit will be'clear that the disk must cause three times the number'ofcurrent interruptions caused by the disk 46, or, to put in the phrase ofcycles, the grooved periphery disk l8 must represent tnree cycles if itis to have a rate three times that of the disk 46, the latterrepresenting but one cycle, already point Of course the live, ten andfifteen instance ed out. cent rates have been chosen in this merely forthe sake of illustration and any convenient ratio of rates may beadopted. To do this it is merely necessary to make the properarithmetical calculations With respect to the number of deviations inthe grooved peripheries on the severe]. disks. Mounted on the timecontrolled shaft 49 is also the time disk 50 which is similar inconstruction to the rate disks. As will be seen from Fig. 1, the groovedperiphery of this time disk is identical with the grooved periphery onthe disk 47. This is purely a coincidence and is the result of theassumptions of the different rates to be represented by the rate disks,to-

the assumption of a certain speed at WiKlCli the shaft d To put itconcretely-for t'ie sake of illustration l have assumed that the timeshaft makes one revolution in ths' of an hour. F or convenience haveadopted of an hour as the unit of time, and a five cent rate as the unitof wages, or in other Words, the unit of time andthe unit Wages are eachrepresented by a cycle, that is to say by ten current impulses orinterruptions. l'nesmuch as the time shaft represents in one olution twounits of time, disk 4-7 will repr esent two units of Wages because'eachof these disks represent two cycles. is for this reason, therefore; thatin 'tl e instance shown, the number of deviations on the of the timedisk is the so it? i re her of deviations on the perip disk -17 Upoi'iother {SS With than those above disk Will, ofcourse, hay

In order therefore, that there may besynchronismbetween the by step movement or" the rat .ict disk, l have provided asynchronizing arrangement in the shape of the electro-magnet 23 and itsappurtenances. In order to understand how the electro-me 'net etlectssuch synchronism let it be assumed that the parts as shown in Fig. 2 areready :tor operation upon the beginning of a cycle of impulses. Thefirst impulse sent through the windings 19' and 23 will, alreadymentioned, rock the armature to move the arm 2? out o:" path of theengaging lug 12.

From this it will be seen thatthe ninth and tenth impulses of device will have to be actuated in anoppoeach cycle are what might be termed emeri gency impulses, whichserve to operate the l ratchet wheel only in case one or more of l thefirst eight impulses failed to produce 1 operation of the ratchet wheel.0?? course if j the first eight impulses have caused the ac- I tuatingpawl to move the ratchet wheell through a distance of eight teet (inwhich 1 have trav- M, event any one projection 12 rill cled through anarc of 90 tenth impulses will be losting operation of the cerned. Thisis due t tae :act thatunder normal conditions, the projection 12 will atthe eighth impulse be brought against the obstructing end of the arm 27.By thus making sure that every cycle represented on the disks 46, 47, 48and 50, will cause the ratchet device to be moved throu h a distance ofeight teeth, I establish syncnronism between the rotation of the timecontrolled shaft l9 on which the disksare mounted and the actuation ofthe ratchet wheel ()1. operating device. I

It will be readily apparent from Fig. 5 where a convenient form ofdi'tlerential gearing is shown, that if the ratchet wheel shown in saidfigure is normally actuated to move in a direction away from theobserver, the ratchet wheel whose pinion engages the bevel gear 10 mustmove in an opposite direction, or, in other words, if the first of aseries of register operating devices is actuated, in a certaindirectiomthe succeeding each register I wheel of any particular registerope 'ating l l l l site direction, while the next succeeding devicewill, of course, be actuated in the same direction as the first one ofthe series. As just explained, this movement in opposite directions ofeach pair of succeeding register operating devices is, in this instance,necessary by virtue of the differential gearing that connects theratchet wheel of one device with that of thenext device in the series.

The construction shown in Fi 4; is for the register actuating devices somodil" from that shown in Fig. 2 that th Will normally operate in thedirection inn x byhe arrow, and which direction, as ll observed, iscontrary to that iantee o7 ,Ithielarrow in Fig. 2. Inasmuch c in of'theparts in Fig. 4 are identical in so ture and operation with cert ll. theL in Fig. 2, it will not be necessary to oesc.

Fig: 4 with such minute deta l as was re sorted to in connection with Fg. 2. It will i J" .v master cloch of speed than the be noted that inFig. i the arm or extension 21a which carries the armature portion 21bis pivoted at 210 so that upon energization of the magnet, arm 21a willbe rocked to the left into the position indicated partly by dottedlines. This movement of the arm 21a to the left will allow the actuatingpawl 22 to ride over the periphery oi the ratchet wheel into engagementwith the next tooth on the left. Upon deenergination of the magnet thespring 28 will draw the arm back to the right into i112 position inwhich it is indicated in Fig. l. This movement of the arm 21a to theright will cause the pawl 22' to drag with it the ratchet wheel throughthe istance of one tooth. It will be noted tl it the forward end of thepawl 22 cara projection at its forward end, which into the recess of twoadjacent Backward movement of the ratchet wheel is prevented by theretaining pawl 29 pivoted at 30. In order to cause the proper projection12 to rest against the obstructing end of the arm 27 at the eighthcircuit interruption of the cycle, I have given this end of the arm 27the shape indicated at 27a in Fig. at. It will be seen that thisdownwardly projecting portion 270. constitutes a barrier to the furthertravel of the associated projection 12 when the two parts have arrivedin engagement with each other. A rod 31 similar to the rod 31 isprovided to lift the arm 27 retaining pawl 29' and actuating pawl. 22out of engagement with their cooperating parts of the ratchet wheel. Thepeculiarly shaped extension 3t has its slotted arm 35 loosely connectedwith a lug on the retaining pawl 29. The cent :11 portion 36 of theextension 3% is provided with a slot engaging lug on the arm 27'. Theaterally extending arm 37 on the extension engages at its tree end a lugon the actunting pawl 22. it will thus be seen that raising the rod 31"will remove the arm 27,

i and the pawls 29 ahd 22" from engagement with tie correspondinglycooperatiing portions of the ratchet wheel,

' into three groups of three '66, 68 and 70 are 'means of ance 57 andcauses the motor to slow down by virtue of the resistance 57, beingplaced in the circuit. il ith the motor thus slowed down, the shaft 5L9will rotate at a lower speed than the clock driven shaft 53, with theresult that the central wheel of the differentials 54 will rotate in theoppositedirection, thereby moving the pr jection 58 away from the springblade 59 and closing the short-circuit around the resistance 57. Thiswill cause the motor to speed. up again and rotate the shaft 4-9 ahigher speed than the speed of the shaft 53. @f course it will heunderstood that although the shaft 49 will rotate at speeds that are nowhigher than the uniform speed of the shaft 53, yet the resultantrotation of the shaft 45) will be the same as the rotation of the shaft53, thereby producing rotation of the disks 46, e7, 48, and 50 at auniform rate of speed.

I will now describe in detail the operation of my system as representedin. the embodiment shown in Fig. 1. Associated with the groovedperipheries of disks 46, it, 5 8, and 50 are spring contacts 61, 62, 63,and 6st, respectively. The free ends of these contacts engage in theperipheral grooves on th se disks, and as the disks are rotated thesecontacts are moved to one side or the other according to the deviationsin the grooves. When spring contact 61 is moved to the left, ii engagescontact 65', and when moved to the right it engages. contact 66.Similarly, a pair of contacts 6'? and 68 are associated with the springblade or contact 62, a of contacts 69 and 70 are associated uponopposite sides of the contact 63, and finally a pair of contacts 71 and72 are associated with contact 64. It will be observed that contacts 69,6?, 65 and 71 are all connected with the conductor 73 which leads to oneterminal of the battery T4. The contacts 72,

all connected with the conductor 75 which leads to the opposite terminalof the battery 74. 'l he battery is, for convenience, shown grounded 76.Contact 64 of the time disk 50 is connected with conductor 77, to whichare connected all the tip contacts 78 of the series of jacks shown. Thecontact 63 is, by means of the conductor 75), connected with theconductor 80. To this conductor are connected-the three sleeve contacts63. The contact 61 is connected by conductor 81 with condictor 89 whichhas connected thereto the three sleeve contacts (31. Contact 62 isconnected by conductor 83 with conductor which has connected thereto thethree sleeve contacts 62. It will thus be seen that the series of ninejacks, shown in the figure, is divided jacks each. 6f course it will beunderstood that this precise number in the series and the division intoa c rtain number of groups is purely arbitrary, it having been resortedto in this in l l l l t stance solely as a matter of illustration. Inorder to avoid unnecessary multiplication or circuits in Fig. l, l haveconfined mysell: to

settin forth an embodiment of my invcntion as it would be used in thecase of three workmen or employees whose time and wages are to be takeninto account. '-lhc number of jacks in the series, of course, do pendsupon the number of employees of whose time and wages the system isarranged to take care. The number of groups into which the series ofjacks is divided dcpends upon the number of different rates whichworkmen are employed in any particular factory or place of employment.lnasmuch as I have selected three different rates, the series of jacksis naturally divided into three groups, each group representing a7articular rate. Thus, for instance, the first group of jacks whosesleeve contacts are indicated by 62' represents the rate of the wheel47. in the particular instance given this would be a ten cent rate. Thegroup of jacks whose sleeve contacts are indicated by 61 represents therate of -the disk l6. Finally the group of jacks whose sleeves areindicated by represents the rate of dislt Suppose now that the plug ahas been inserted as shown. In this case the wage register that will beactuated because of the insertion of the plug will operate at the raterepresented by wheel 47. The circuits may be traced as follows: For thesake of conenience we start at the ground 76, through the right half ofthe battery, through conductor 75, into conductor 75 to the point 75'.At this point, assuming that the position of the disk is such that thespring blades (51 and 62 .will be forced to the right into contactrespectively with '72 and G8, the current divides as follows: A portionflows through contact 68, across the contact 62 into conductor 83, intoconductor 31-, thence to the sleevecontact (52, from there intoconductor 85, through the wage register i i/w, into conductor 86 to thepoint 87. If the worlrmans switch 88 is closed, the current will findground through conductor 89 at 90. The circuit as thus (raced willzu-tuatc th wage register jaw. The other portion of th current whichdivided at the point 75 will flow as follows: into conductor T5 tocontact 72, over to contact (34-, to conductor 77 to the tip contact 78,thence into conductor 92, through the time register it, conductor 91,through the workmans individual time register A and from there to theground through and 90. This last traced circuit, it will be noted, willactuate the workmens individual time register A as well as thecorresponding time register fit.

in order to trace the circuits completed by the plug a when the timeshaft is in such a position that the spring blades 64 and 62 are forcedto the left into contact respcctively with 71 and 67, let us begin asbefore with the ground 76, thence through the left half of the battery,through conductor 73 to the point 73. Here the current divides, aportion of it being traced through conductor 73', contacts 67 and 62,conductor 83, conductor 84, sleeve terminal 62, conductor 85, wageregister Aw, conductor 86, switch 88, thence to the ground through 89and 9G. The other portion of the current from thg vJoint 73 is tracedthrou h contact 71 an 64:, conductor 77, tip contact 78, conductor 92,time register At, conductor 91, worknicns individual time register A,thence through switch 88 and conductor 89 to ground 90. From this itwill be seen that this last set of circuits is substantially identicalwith the first set of circuits traced, the only difference being in theportions of the circuits passing through the spring contacts (i l and62, which contacts are moved either to the left or to the right,according to the position of the rate disks, and the time disks. Fromwhat has been explained before with regard to the configurations of thegrooves on the peripheries of the time disks and the rate disks, it willbe observed that during one cycle the contacts will be moved first threetimes to the right, then seven times to the left. From the tracing ofthe above circuits it will be clear what the circuits wound be if plug6' or plug 0 were inserted in the jack in which plug a is shown insertedin Fig. 1. Of course if we imagine plug 2) in serted in the first jack,the circuits would pass through the wage register Ba: and the timeregisters B and B25. The circuits through these registers may be readilytraced thus: from the sleeve of plug 1) into conductor 91, throughregister Bw, conductor 92, through switch 93, (provided the same isclosed, as it would be upon the workmans arrival) thence into conductor89 to ground 90. From the tip of plug Z) the current may be tracedthrough conductor 9%, through time register Bt, conductor 95, timeregister B, switch 93 to ground 90. The circuits from ground 76 of thebattery to tip and sleeve of the plug 1) would be the same as thosedescribed in connection with plug a. As previously mentioned the seriesof jacks is divided in the present instance, into three groups of three.jacks each, each series representing a certain rate. As shown in thedrawings, plug a is inserted in the first group, which means that thewage register controlled by the plug operates at a ten cent rate. Nowplug (i might he inserted in any jack of the other groups to cause thewage register A10 to operate at a different rate. To illustrate thisoperation at a diff-ercnt rate I have shown the plug 0 inserted in thegroup of acks which corresponds with the live cent rate. Let us newtrace the va rio'us circuits with the plug 0 in the position shown inFig. 1: Startingwith ground 76, current will pass through the right halfof the battery into conductor 75, thence into conductor to the point 96.At this point the circuit divides, one portion passing into contact 66over to contact 61, (during the portion of the cycle in which thecontact 61 's forced tothe rightby the deviations in the grooves) thenceinto conductor 81, conductor 82, sleeve contact 61, conductor 97, wageregister Cw, conductor 98, switch 99 (which of course would he closed)thence to the ground 90. The other portion of the circuit that dividedat the point 96 is traced follows: point 96, contacts 72 and 6%, (duringthat portion of the cycle in which the contact til is forced against thecontact 72) thence into the conductor 77 to the tip contact 78, throughthe tip of the plug into conductor 100, time register Ct, conductor 101,into the workmans individual time register C, and thence through switch99 to the ground. During that portion of the cyclein which the springcontacts working in the grooves on the disks are forced to the left, asviewed in Fig. l, the circuits would he the same except that'instead ofpassing through the right half of the battery, the circuits would betraced from the ground through the left half, as already indicated inconnection with certain circuits traced through the plug a. From thecircuits that have thus far been traced, it will be noted that plug 0:controls registers A, AL and Aw; plus 1) controls registers B, Bt, andBw; and plugnc controls registers C, Ct, and Cw. In other words, theParticular plug assigned to each workman will control his particularregisters.

As may be seen from Fig. 1, any one of the plugs a, Z) and 0 may beinserted in any one of the series of jacks so that a register of anyworkman may be made to operate at any one of the desired rates. Thus ifit is desired that the workman whose plug is a shall work at say afifteen cent rate, all that is necessary is to take plug 0, and place itin any one of the group of jacks representing that particular rate. Inthe instance illustrated that group comprises the last three of theseries of jacks.

At this time I desire to call attention to the diagrammaticrepresentation of the registers in Fig. 1. It is intended that thecircles A, At, etc, together with their corresponding gear connectionsindicate diagrammatically the register operating de vices and theirappropriate gearing, as shown in Figs. 2, 3, and l. The time registersAt, Bt and Ct tota lizc into the SUI11- mation time register T in orderto have an indication of the total amount of time con sinned by theworkmen. as shown by each worlnnans individual register. The onlydifference hetweenthe time registers A, B,

and C and time registers [125, Bi and Ct is that the first set of timeregisters has each register independent of the other, hile in the secondset of registers the registers are ditt'erentiully geared together so asto control. the actuation of the summation re ister. The summation Wageregister l is geared to the individual Wage registers iixw, B20 and Cw,to indicute the total or sum of their zictuutions.

The six registers indicutdd at the right 0:"

registers 7'1, f2 and give indications of position in which it is shown,for the sake of illustration, in'Fig. 1, it would be h? necessary toplace plug a in one or he erks 102, 1.03, or 104i, these controllingrespectively the job registers jl, j? and j it, now, plug a be insertedin the the circuit through tl e job register 7'1 would be traced asfollows: l roin conductor 85, the circuit as previously traced inconnection with plug a would divide the point 105, a portion of itpassing into the wage register Aw, as previously described, the otherportion. passing from point 1.05 into conductor 1%, the tip of plug a,tip contact 107, conductor 108, through job register /1, conductor 109,the sleeve contact 110 of jack 102, through the sleeve of pluga,conductor 111 to switch 88, themes through conductor 89 to the ground90. inasmuch as the retest which the register or registers controlled bythe plug a is primarily dc termined by the particular jack into whichthe plug is inserted, it is evident that the l particular 'job registercontrolled by e plu a would essentially operate at the some rut .ns thewage register controlled by the plug, a, Inasmuch as it is the plug athat do" terinines the rate of actuation of the correspending'wegeregister any job register which may be placed in circuit by the plug acan operote'only at. the same rate at which the wage register isoperating, as determined by the plug a. The job plug 7) is essocieted"with the Wcrlunen s plug 6 in the some manner that job plug a/ isassociated with the plug a, as above described. Siniilerly the job pluga is assoi'ziuited with the Workniens plug (2.

With plug 7) inserted in any particular pick in the series,

and the job plug Z) inl l l l conductor 121,

as described in connection with Fig. 1

in lhg. Y let it iodicece the Worlununs 1ndividuel time re, Let it beassumed that the workinsns switc 1 122 be closed and the plug a insertedin jack 128. The circuit would then be traced from the battery LO thencethrough the the sleeve contact 12%,

from there into the wage register Aw, ,through the conductor 126,individual time register A. conductors 12?, 128, 129, through the tip ofjob plug uj. Tow unless this job plug is inserted in one of the jobjacks, the circuit througn the worlcnmns individual time register it andhis wage register lice would not be completed, and the Wage registerwill show no uccijunuletiou of Wages. In order that this Wage registermay be actueted, it is necessary that the worlnnun he 1ZS- signed tosome particular job. Let it, thereore, be assumed that this the case nndhat the job plug aj is inserted in the jock tact 134 of the jack 123through the time register At, conductor in series with the correspondingwage be'completed unless both as illustrated in .isters J3 and J6totalize into the summation gear 142.

In this case the circuit would be traced 1 from conductor 129,through the tip of plug 1 ay', the tip contact 131, conductor 132,through the time register jt, conductor 133, thence to ground 134,completing the circuit through the battery. The circuit from the tipconis as follows: through the tip of plug a, conductor 135, 13G. switch122, conductors 137, 138, 139, sleeve of job plug Aj, sleeve contact140, conductor 1 11, wage register in), thence to the ground 134. Fromthis tracing of the circuits as arranged in Fig. 7, it will be observedthat the workmans wage and time registers arg ant time registers 0t anyparticular job so thatthe circuits through these registers cannot theworkmans plug and the job plug areinserted in the desired jacks. Themodification presented in Fig. 7 shows the flexibility of my system theembodiment of Fig. 1. Directing attention to Fig. 1, it will be observedthat the job registers jl, '2 and 7'3 totalize into the register J3,while the individual job registers jet, and 713 totalize into thesummation register 56. These reg- 7 The summation wage register t andthe summation job register J t are connected together by theditterential Now these summation registers are arranged to be actuatedin opposite directions so that the register actuated by the differentialgear 142 will indicate the ditleriob register Jt.

ister Wt and the amount of actuation of register J t. Under normalconditions these registers should give corresponding indications so thatthe central wheel of the differential 142 would remain stationary andthe register X remain idle. However, it any workmans plug has beeninserted and his particular wage register accumulates without his havingbeen assigned to a. job, then the which excess would be indicated by theregister X. It will thus be seen that this register X gives indicationsof unassigned jobs.

It is to be understood that, as shown in Fig. 1, the relation of theregisters is to each other such that additional registers may be addedif desired in any of the series to meet different demands of the system,and, that for any operative condition the end .gear the shafts is to bemovements of the common gears 01 the ditferential mechanism may betransmitted The means which I have provided for de-.

cumulating the registers, or, in other words,

bringing them back to zero, is indicated to be onerated manually, or atleast mechanically as distinguished from anything like an electricallycontrolled operation. 011 one end of the suitably mounted shaft 1-13 isthe gear 111; which by shifting the shaft may be brought into engagementwith the gear 145. \Vhen this engagement between the gears 114': and 145has been effected, the shaft 1 13 is rotated in a direction to causeactuation of the registers mechanically connected therewith in adirection to decumulate such registers. This rotation of the shaft 113in the reverse direction may be done manually, in which case I provide ahandle 1:46.

In order to prevent decumulation ot the registers below the zero orstarting point, I have arranged locking means in the shape of av bar 147as shown in Fig. 3. This bar is pivoted at 148 and is provided withthree downwardly exteudin teeth or projections 1 19, 150, and 151. llith the parts in their positions as shown in Fig. 3, that is to say,

in the zero or starting position, the teeth on.

the bar rest in'notchcs 1 52, 153 and 15% re spectively. The wheels 16and 18 during the accumulations of the register rotate in the directionindicated by the arrows. It will be observed that the shape of the teeth1 19 and 151 is such that upon this rotation of the wheels the teethwill be lifted out oi: their respective notches, thus causing no interference with the tree rotation of the wheels during the normaloperation of the register. The projection 150 is provided with no suchcam. surface as the teeth 11-9 and 151 are provided with, but. the notchor recess 150 in the wheel 17 is made sulliciently large to permit acertain amount of rotation of the wheel 17 before the tooth 150 engagesthe wall of the recess 153. This play of the tooth 150 in the recess 153is necessary in order to allow suthcier t rotation of the wheel 16 topermit tooth 151 to be forced out of its corresponding notch in thewheel 16. lVith the bar 147 thus raised, tooth 150 will be out of therecess 153 and wheel 18 will be free torotate just as the wheels 16 and17 will However, during decumulation of the register, themomcnt that theparts have reached the position as indicated in Fig. 3,,

the locking bar 147 will. drop into locking position, so that anyfurther rotation of the wheels in a direction opposite to that indicatedby the arrows is positively prevented by this bar. In other words, whenupon decuinulation a register has reached its zero position, the wheelswill be locked against further decumulation.
